Fountain brush



Patented Dec. 23 1930 UNITED STATES PATENT OFFICE I JAMES FLOCKHART, SANFRANCISCO, CALIFORNIA, 'ASSIGNOR TO THE FLOCKHART COMPANY, OF SANFRANCISCO, CALIFORNIA, A CORPORATION OF CALIFORNIA FOUNTAIN BRUSHApplication, filed September 30, 1929. Serial No. 396,082;

This invention relates to improvements in fountain brushes 7 forapplying paint or heavy ink to surfaces. It relates more particularly tobrushes or spreaders of the Tqkueegee type,- used in stencil work, andthe Among the objects of the invention is to provide a fountain brush inwhich the feed of the paint is adjustablycontrolled at all times.

Another object is to provide separate compartments in equal or differentproportions for severalkinds of paint.

Another object is to provide a brush of this type of simple design andstrong construction, and one which may be readily taken apart forcleaning.

Other objects and advantages will appear as the description progresses.

In this specification and the accompanying drawings, the invention isdisclosed in its preferred form but it is to be understood that it isnot limited to this form, because it may erably castin one piece oflight metal.

be embodied in other forms.

this invention in whatsoever form it may be embodied.

In the accompanying one sheet of drawing:

'Figure 1 is a front elevation of the brush.

Figure 2 is a section taken on the line ,lI-II of Figure 1. 4

Figure 3 is a rear elevation of the brush.

Figure 4 is a plan of the brush having parts broken away for purposes ofillustration.

The main body 1, of the brush, is preft has the ends 2 and 3 joined bythe upper front side 4 and the curved lower front side 5, which projectsto form the front wall of the paint reservoir 6, open at the top 7 toreceive the paint.

The back wall of the reservoir consists of a plate'8 having a rubberstrip 9 clamped on its lower edge by the plates 10 and 11, by means ofthe screws 12. The rubber strip projects below the point 13 of the side5.

The plate 8 is pivoted on the ends 2 and 3 It is also to. be understoodthat in and by the claims following the description, it is desired tocover by means of. the lugs 14- and 15 fixed to the plate, and the rod16 which extends through thelugs and the ends. A spring 17 acts to holdthe lower end of the plate against the side .5. The lower edge of theplate 11 en- 1 jection'19 andserves as a handle for the use of theoperator when pressing in the top of the plate 8 to open the lower endto allow paint to flow out.

Screws 20 and 21 in the plate 8, engaging the back 4 are provided toadjust the amount of the opening and thereby the amount of paint fedout. The partitions 22 and 23 are laterally slidable on the rod 24;. Therod 24 engages the enlarged holes 25 in the sides a, 3 to allow for thepartitions adjusting themselves to the inside of the reservoir and tothe plate 8 when the plate 8 swings open. Only slight adjustment isneeded as the paintis heavy and does not require very tight jointsbetween the partitions and the walls.

In the operation of the brush if one kind of paint is to be used thepartitions are moved along the rod to the ends and the res ervoir isfilled. But if two or more kinds of paint are used, the partitions aremoved along the rod to divide the reservoir into two or morecompartments, each to be filled with I the required color of paint.

The brush is moved over. the surface to be painted, in the directionindicated by the arrow, with the plate 8 pressedin at the top untilthescrews 20 and 21 come in contact with the front member 4 to feed thepaint to the surface and distribute it by the squeegee 9.

The action of this brush is in reality automatic; as the brush is movedin the direction of the arrow with the rubber strip in contact. thefriction tends to swing the lower end of the plate 8 back and allow thepaint to feed. Near the end of the stroke of the brush over the work theplate is released and the spring throws it to bring the lower edge ofthe plate 11 against the edge 18 and the rubber strip against the edge13 of the reservoir to cut off the flow of paint. To get the rightamount of paint for each stroke, the screws 20 and 21 are adjusted sothat the opening of the plate is regulated to deliver the amountrequired.

Having thus described my invention what is claimed and desired to secureby Letters Patent is: I

l. A fountain brush of the class described,

comprising a fiatbody memberhaving an,

open paint reservoir extending across its lower end, a plate extendingacross the body member from side to side, and top to bottom, and formingone wall" of the reservoir, '-a transverse pivot member intermediate thebOttOIIl, a spring to the plate in contact with the bottom of thereservoir, and a rubber spreader securedto the bottom of said plate.

7 2. A'fountainbrush of the class described, comprising an open paintreservoir, a handle portion extending upward from said reser voir, apivoted plate in the handleportion and extending downwardly to formtherear wall offthe reservoir, adjustably spaced partitions in saidreservoir, a resilient, spreader secured to the bottom edge of saidpivoted plate, and means to tilt said plate totailow paint to feed fromthereservoir to be spread by said spreader. i

,3. A fountain brush of the class described,

comprising a plate having. a resilient strip secured to the bottom edgethereof, a body member havingan open paint reservoir pro jectingtherefrom, said plat-e being pivoted to and forming the back wall ofsaid reservoir, means to hold said plate. in the closed position, meansto move said plate to allow a "predetermlned amount of paint to flowfrom said reservolr as'the brush is moved over the surface to bepainted.

4. A'fountain brush of the class described, comprising a body member, anopen paint reservoir, a movable plate pivoted to said body memberandforming the back wall of said reservoir, a resilient strip secured-tothe lower edge of said plate and in substantially the same plane'as saidplate, means to move said plate to permit the flow of paint, and

adjustable means to limit the throw of said plate.

5. A fountain brush of the class described, comprising a body member, areservoir'for holding paint in said body, a pivoted plate forming thebackv wall of said reservoir, a weight forming part of the top of saidplate to hold said plate in contact with the bottom of said reservoir,aspring to augment the effect of saidweight, and a resilient spreadersecured to the lower edge of said plate.

In testimony whereof I have hereunto set my hand this 20th day ofSeptember, A. D. 1929. V Y i JAMES'FLOOKHART.
